Among campaign analysts, the topic of the last week has been the possibility of Clinton dropping out of the race.

Her campaign, however, has insisted that a clear victory against Barack Obama is still possible, but through untraditional means.

Facing a deficit in pledged delegates, the official measurement by which a nominee is chosen, Clinton and her campaign have argued that she may win without them after the remaining 10 primaries have been held, if the decision comes down to a measure of the popular vote.

Yet, Clinton is currently trailing Obama in the popular vote by about 700,000.

While this scenario would not secure Clinton the nomination, she and others have argued that a popular vote win could help bring superdelegates over to her side, overturning Obama’s delegate lead.

Support from the superdelegates, the 793 elected officials and party leaders charged with deciding close races, would provide the New York Senator the only possible path to the Democratic nomination.

With polls narrowing in Pennsylvania, the site of the largest remaining primaries—Clinton’s best chance of closing her popular vote and delegate gap—some observers have pointed to an all out collapse of the Obama campaign as her only path to victory.

U.S. News and World Report writer Michael Barone gives his take on how Clinton could clinch the popular vote in the remaining primary states, allowing her to argue to superdelegates that she is the more electable candidate.

Adam Nagourney of The New York Times explains that Clinton would not only have to win sizable margins in the remaining primary states, erasing Obama’s popular vote lead, but also convince the remaining superdelegates that she is the more electable of the two candidates. Nagourney states that this would require an Obama campaign meltdown akin to the recent “subprime mortgage market.”

Sean Oxendine breaks down the primary states yet to be decided by population, county, race and past voting records and finds that Hillary Clinton has a chance of winning the popular vote should trends and polls not shift too much between now and the contest – a valid argument, says Oxendine, for her to keep campaigning.

Democratic Party Chairman Howard Dean told CBS News that the superdelegates should make up their mind about who they would like to support before July, but the Clinton campaign has stated plans to run until the national party convention in late August.

Former White House advisor Karl Rove told Fox News’ Hannity and Colmes that Clinton should indeed stay in the race given the number of contests yet to be decided, and because it would benefit the Democratic Party to not be seen as pushing her out.

The Pittsburgh Post Gazette responded to calls for Clinton to step aside with the observation that “this fight isn’t over” and that the New York Senator is right to keep campaigning, at least until their state’s contest has been held.

Dwayne Wickham of USAToday suggests Clinton stays in the race despite her obvious deficit, citing the fact that while she will not be able to earn the requisite 2,025 pledged delegates required to secure the nomination, neither will Obama, leaving the decision to the superdelegates and offering her a slim chance of winning.

A Politico running tally of superdelegates shows Clinton with a lead of 31 – a lead she would need to widen to assure victory. However, the difference would not completely close the gap between the two candidates, and there are still 255 superdelegates who have not issued formal endorsements of a candidate.

The New York Times Election Guide provides a breakdown of each candidate’s number of pledged delegates and superdelegates according to state, showing Obama with a 156 delegate overall lead, a number Clinton’s campaign has argued is secondary to what she considers her superior electability.
